The "Beautiful Girls" singer has been at Jackson Memorial Hospital since the May 29 accident. Officials say Kingston, 21, and 23-year-old Cassandra Sanchez were injured when their Sea Doo struck the bridge connecting Palm Island with the MacArthur Causeway.

Both Kingston and Sanchez were pulled from the water by a helpful boater.

Kingston had been rushed to the hospital in critical condition but has improved steadily over the past few weeks, hospital officials say.
